GUN SIGHT.

Application filed August 10, 1925. Serial No. 49,464.

This invention relates to improved sights for use upon a gun, therebeing a sight on the stock, one on the rear or inner end portion of thebarrel, and one at the forward or outer end of the barrel.

An advantage is derived by utilizing a stock sight which is providedwit-h a lens and is of telescoping construction permitting it to beextended to the desired level, together with a means for mounting thesame in a manner to permit it to be instantly folded down against thestock to render it out of the line of vision of the gunner, or to bedisposed in vertical position, to render it operative.

The central sight on the inner end portion of the barrel ischaracterized by the presence of a magnifying glass capable of beingadjusted back and forth and to render it advantageous for long rangeshots.

Other features and advantages of the invention will become apparent fromthe following description and drawings.

In the accompanying drawings forming a part of this application and inwhich like numerals are employed to designate like parts throughout thesame:

Figure 1 is a side elevation of a conventional form of rifle or the likeequipped with an arrangement of sights constructed and arranged inaccordance with the present invention.

Figure 2 is an enlarged detail elevation and sectional view of thecentral sight.

Figure 3 is an end elevation of the same looking in a direction fromright to left in Figure 2.

Figure 4- is a top plan of the same.

Figure 5 is a side view of the sight on the stock. I

Figure 6 is a central vertical section of the same with parts inelevation.

Referring to Figure 1 it will be seen that the sight on the stock isrepresented generally by the reference character 1, the central sight bythe reference character 2 and the usual stationary front sight by thecharacter .3. For convenience, the sight 1 will be hereinafterdesignated generally as the stock sight, while the adjacent one will bereferred to as the central barrel sight. The sight 2, last named,comprises a base 1 which is slidably mounted upon a guide rod 5 fastenedto the top of the barrel 6. This rod is provided with a transversedovetailed key 7 fitting into a correspondingly shaped key-way in thebarrel, thus affording a connection for one end. The opposite end isfastened by a screw or appropriate fastener 8. Obviously, this base isadapted to be moved back and forth on the guide rod and it is held indifferent set positions by a set screw 9. At the opposite end, it isformed with upstanding cars 10 with which a member of right angularformation has pivotal connection. This member comprises a frame 11 andan integral sight 12. From Figure 4, it will be seen that the sight 12has its free end cut out or provided with a central V-shaped notch. Theframe 11 constitutes a holder for a magnifying lens or glass 13 which isrcmovably held in place by a ring nut 14. This ring nut is provided withcircumferentially spaced spanner wrench notches. A removable pivotpintle 15 passes through the cars 10 and the right angular member forpivotally mounting the same in place. This pin is provided on one endwith a T-shaped head 16 forming a looking key and this extends through aslot in one of the bearing cars 10 and into a groove in the adjacent endof the right angular member. In this way, the last named member may beheld in either of its adjusted positions. For the purpose of holding thekey in place, we provide a flat spring 17, the free end of which bearsagainst the key 16. With this arrangement it is obvious that the lens 13may be dis posed in the right angular operative position shown in fulllines in the drawing or it may be swung down and against the guide stripas indicated in dotted lines in Figure 1. At this time the part 12 whichis carried thereby swings up to vertical position to render itoperative. therefore alternatively operative. The inner edge of the head16 of the key is wedgeshaped so that all that is necessary is to pullbackward on frame 11. Referring now to the sight 1 and confiningattention more particularly to Figures 5 and 6, it will, be seen thatthe same comprises an attaching bracket or mounting 18, the sideportions of which are fashioned to receive the lower end of a cylinder19. By noticing Figure 6 particularly it will be seen that a pivot pin20, somewhat like the one already described, affords a connectionbetween the cylinder and the mounting. The pin also carries a lockingkey or head 21 bevelled to fit into a V-shaped groove 22 formed at theThese two details are proper.

spring 24 surrounds this end portion and is fitted lnto a socket formedin the mounting.

This spring serves to maintain the key 21 normally in locking contactwith the cylinder. A plunger 25 is slidable in the cylinder and isprovided at its top with the sight This sight comprises a ring 26 inwhich a glass lens 27 is clamped by a ring nut 28. The plunger 25 isprovided with diametrically opposite pins 29 slidable in slots 30 formedin the cylinder. The upper end of the plunger is screw threaded asindicated at 31 and there is a swivelled nut 32 on the upper end of thecylinder cooperating with the plunger for feeding it up and down againstthe tension of the spring 33 in the bottom of the cylinder. Bypreference, one side of the screw threaded part 31 is fiattened asindicated at 34: and this flattened part will, in practice, be providedwith graduations whereby the height of the sight may be accuratelymeasured.

From the foregoing description it will be seen that the inventionrelates to what may be said to be a peep-scope sight, or a combinationpeep and telescope sight. One advantage is that the regular open sightcan be used if the rifleman so desires and the sights can be carriedinto the woods without more danger to them than the ordinary sights. Itgives the user a chance to always have a telescope sight with him forlong range shots. The front sight stands out sharp and clear and as whenusing the ordinary peep sight, the front sight is the only one to bewatched. In other words, by using it, the user gets peepsight accuracygreatly magnified. The sights have an automatic lock on them whichpermits them to be disposed in vertical operative position or inhorizontal inoperative position. Very little time is required for thetransformation. Undoubtedly, careful consideration of the description inconnection with the drawing will enable persons skilled in the art towhich the invention relates to obtain a clear understanding of the same.Therefore, a

more lengthy description is thought unnecessary.'

What we claim as new is 1. In combination, a gun embodying a barrel anda stock, a sight c arried by the stock, a front sight carried by thefront end of the barrel, an intermediate central sight carried by theintermediate portion of the barrel, all of said sights being located inlongitudinal alinement, said central and stock sights embodyingcomplemental telescopic lenses, said central sight being adjustable in adirection longitudinally of the bar-- rel, and said stock sight beingadjustable in a vertical direction at right angle to the barrel.

2. As a new product of manufacture, an attachment for a gun barrelcomprising a metal strip of dovetailed cross-section adapted to bedetachably fastened on top of a gun barrel, a transversely disposed keycarried by one end of the strip and adapted to fit into a keyway in saidbarrel, a slide of right angular form, one leg of which is in the formof a ring-like frame which is internally screw threaded and providedwith an inturned flange, the other leg being in the form of a notchedplate, a lens fitted into said frame, a clamping ring therefor threadedinto the frame and bearing against the lens, a base slidable upon theaforesaid strip, said slide being pivotally mounted upon said base, andspring-pressed automatically operable retaining means cooperable withthe base and the slide, whereby either leg of the slide may bepositioned vertically for sight.- ing objects.

In testimony whereof we affix our signatures.
